-# REPLACE
+# archtechx/helpers
 
-Simple and flexible package template.
+A collection of helpers we commonly use in packages or applications.
 
-# Usage
+Documentation will come later, currently not intended for public use.
 
-- Replace all occurances of `REPLACE` (case sensitive) with the name of the package namespace. E.g. the `Foo` in `ArchTech\Foo`.
-    - Also do this for file names, e.g. `REPLACEServiceProvider.php`.
-- Replace all occurances of `replace` with the name of the package on composer, e.g. the `bar` in `archtechx/bar`.
-- If MySQL is not needed, remove `docker-compose.yml`, remove the line that runs docker from `./check`, and remove it from the `.github/ci.yml` file.
-    - If SQLite is wanted, change `DB_CONNECTION` in `phpunit.xml` to `sqlite`, and `DB_DATABASE` to `:memory:`.

-## Installation
-
-```sh
-composer require archtechx/replace
-```
-
-## Usage
-
-```php
-// ...
-```
-
-## Development
-
-Run all checks locally:
-
-```sh
-./check
-```
-
-Code style will be automatically fixed by php-cs-fixer.
+Breaking changes may occur, and renamings are likely.
